How to Fix B1302 Accessory Delay Relay Coil Circuit Failure

Introduction

If you’re experiencing issues with your car’s accessory delay relay coil circuit, you may be wondering how to fix it. The B1302 code indicates a failure in this circuit, which can cause problems with your car’s electrical system. Fortunately, with a few simple steps, you can diagnose and fix this issue yourself.

Step 1: Check the Fuse

The first step in fixing the B1302 code is to check the fuse for the accessory delay relay coil circuit. This fuse is typically located in the fuse box under the hood of your car. Use your owner’s manual to locate the fuse and check if it’s blown. If it is, replace it with a new one and see if the code clears.

Step 2: Inspect the Wiring

If the fuse is not the issue, the next step is to inspect the wiring for the accessory delay relay coil circuit. Look for any signs of damage or wear, such as frayed wires or loose connections. If you find any issues, repair or replace the wiring as needed.

Step 3: Check the Relay

If the wiring is not the issue, the next step is to check the relay itself. The accessory delay relay is typically located in the fuse box under the hood of your car. Use your owner’s manual to locate the relay and remove it from the fuse box. Check the relay for any signs of damage or wear, such as a burnt smell or melted plastic. If you find any issues, replace the relay with a new one.

Step 4: Test the Circuit

If the fuse, wiring, and relay are all in good condition, the next step is to test the circuit itself. Use a multimeter to test the voltage and continuity of the circuit. If you find any issues, repair or replace the circuit as needed.

Step 5: Clear the Code

Once you’ve fixed the issue with the accessory delay relay coil circuit, it’s time to clear the B1302 code. Use an OBD-II scanner to clear the code and reset the car’s computer. This will ensure that the code doesn’t come back and that your car’s electrical system is functioning properly.

Conclusion

Fixing the B1302 code for the accessory delay relay coil circuit failure may seem daunting, but with a few simple steps, you can diagnose and fix the issue yourself. By checking the fuse, inspecting the wiring, testing the relay, and testing the circuit, you can ensure that your car’s electrical system is functioning properly and that the code doesn’t come back.
